164th Ave NE Rechannelization

OVERVIEW

This project revised the channelization on the segment of 164th Ave NE (SR 202) between the intersections at NE 80th St and NE 87th St and provided bike lanes as designated in the Downtown Transportation Master Plan and improved traffic flow through intersections. By using the existing pavement more efficiently, the 164th Ave NE rechannelization transformed an existing Downtown corridor into a complete street for vehicles, pedestrians and cyclists. When paired with the completed 164th Ave NE Extension, the 164th Ave NE rechannelization creates an new north-south Downtown corridor which seamlessly connects Bella Bottega, Cleveland Street and Redmond Town Center.

The revised channelization reassigned the existing pavement width within the confines of existing curbs to provide a single through lane each direction, augmented with a continuous two way left-turn lane with left turn pockets at intersections, and added bicycle lanes on each side of the street. The revision improved motorized and non-motorized capacity, transit operations, and the walking environment by increasing the separation between pedestrians and vehicles and reduced the likelihood of traffic accidents.

Wheelchair ramps at intersections were rebuilt at NE 80th Street, NE 83rd Street and NE 85th St to improve pedestrian street crossing operations. Traffic signals were modified at the three project intersections incorporating new flashing yellow arrow left turn phase to improve operation efficiency. New traffic signal heads were installed at the three project intersections to support the channelization revisions.
